aaH Address MSB: upper byte of the starting address of
the transmitted data
bbH Address: middle byte of the starting address of the
transmitted data
ccH Address LSB: lower byte of the starting address of
the transmitted data
ddH Data: the actual data to be transmitted. Multiple
bytes of data are transmitted starting from the
address.

* The amount of data that can be transmitted at one time depends on the type
of data, and data can be received only from the specified starting address and
size. Refer to the Address and Size given in Section 3.
* Data larger than 128 bytes must be divided into packets of 128 bytes or less. If
“Data Set 1” is transmitted successively, there must be an interval of at least 40
ms between packets.
* Regarding the checksum please refer to section 4 .
